Summary
An outbreak of allergic contact dermatitis in an aircraft factory where epoxy resinimpregnated materials were employed has been investigated. Of 30 operatives, 20 gave positive reactions to the composite material. In these patients, patch tests with epoxy resin 1% (Firma) gave a positive reaction in only four cases. Patch tests with diglycidyl ether of bisphenol A (DGEBA), tetraglycidyl-4-4′-methylene dianiline (TGMDA), triglycidyl derivative of p-aminophenol (TGPAP) and o-diglycidyl phthalate were performed in 18 of the patients. TGMDA, TGPAP and o-diglycidyl phthalate picked up all the 11 patients positive to the composite materials.
These data confirm that the composite materials must be used as is for patch testing due to the unreliability of the tests performed with common epoxy resin 1% in petrolatum. In addition, they indicate that TGMDA, TGPAP and o-diglycidyl phthalate, which are new constituents of carbon fibre epoxy resin system, can be used in order to reveal the sensitization.
